AUTOMOBILE HEATING- APPARATUS.

Specification ofLetters Eatent. JPgtented N 30 1915,

Appiicetion filed December 11, 1914. Serial No. 818,752.

To all whom) it may concern:

Be it known that I, Wnrrrnn a citizen of the United States, and a resident of the city of Portland, State of Oregon, have invented a new and useful Improvement in Automobile Heating Apparatus, of which the following is a specification.

My invention relates to an improvement in means installed in engine-driven vehicles, for-utilizing the exhaust from the'engine as a heating medium.

The object of my invention is to arrange the heating means in the form of a register located'in the vehiclebody, and to adapt the register to be opened and closed at will, for admitting heat into the vehicle body or ex-'. cluding the same, as desired.

a To thisend my invention comprises a heat-- ing drum located in a hcating'opening therefor provided in the vehicle body, the drum being connected in the exhaust conduit of the engine. Above the drum is a grating, and on the drum is a fender circumferentially movable about the drum and partially inclosing the same. lVhen in one position the surface of the drum exposed in the heating opening of the vehicle body is uneovcred, so that heat may be radiated from the heating drum, while in the other adjustment of the fender the drum is covered so as to prevent any radiation of heat therefrom into i the vehicle body.

The details of construction and operation of my device are hereinafter fully explained. In the accompanying drawings, Figure 1 is a sideelevation of an automobile, showing my device used in connection therewith.

This view shows the exhaust pipe of the en-- gine and the location of the heatingdrum, which in this'case is the muffler, relative to the floor of the car. -The door of the tonneau of the machine is shown open and it will be seen that my device is arranged so as to replace the ordinary footrail. Fig. 2 is a larger sized view taken approximately on the line 2-2 of Fig. 1. Fig. 3 is a transverse vertical section taken pn the line of Fig. 2. Fig. 4: is an elevation showing the revoluble sleeve which incloses the muffier, and which is adapted to direct the heat in the direction desired, and Figs. 5 and 6 are sectional views taken approximately on the line 55 of Fig. 4, showing the extreme positions to which the sleeve may be rotated.

a, represents an automobile of standard construction in whichmy device is installed.

Z), is the exhaust pipe leading from the en J. Roo'rs,

' gine, a is 'tlie mufiier and (l the pi e connects directly with the cylinder, 6, and I the pipe, d, connects directly with the cylinder 9. The cylinderse and f are provided with holes 6 and 7 respectively, through which the gases pass intheir transit from the pipe 6 to the pipe 03. Concentric with, and inclosing the cylinder 9', is a revoluble cylinder, 7'. Said cylinder, 7', is provided with a cut-away portion, is, and slots on and oathese latter permitting the cylinder to be rotated a maximum degree relative to the fixed pipe, d. Said cylinder is provided with a lining of asbestos, as indicated. by 0. Furthermore, the cylinder is provided with a peripheral flange p, and an extension spring 9, encircles sa'idsleeve, being confined between the sleeve 9 and the cylinder head i. The expansion of this spring tends to act as a retarding device to hold the cylinder in I any position to which it has been rotated.

On one end of the device is a projection r,

adapted tobe operated by the foot erase" 'which the projection r is adapted to move.

The operation of mydevice is'as follows:

When the atmosphere of the car is suiii-' ciently warm, the cylinder is rotated so as to bring it in the position shown in Figs. 2 to 5 inclusive. The radiated heat from the muiiier is then directed downward beneath the floor of the car. When, howeverfit is desired to utilize this heat, the cylinder is rotated to the position shown in Fig. 6.

The radiated heat from the muffler is then conveyed directly to the body of the ear and serves as a heating medium. The cylinder maybe rotated any distance as desired, for partially or entirely opening or entirely closing the register, and thereby regulating the heating of the body of the car.

I claim:

1. In an engine driven vehicle, a body provided withan opening, a drum located ,the drum within the vehicle, aslot in the i grating and a pin projecting from the fender when moved to exposed the drum within the vehicle. 2. In an engine driven "vehlcle, a body provided with an opening, a drum located in such opening and exposed partly Within and partly without the vehicle, said drum being connected in the exhaust conduit of the engine, a fender movable circumferentially about the drum and partially inclos-- ing the same, said fender adapted to cover that portion of the drum without the vehicle when moved to exposed the drum within the vehicle, and means for restraining the circumferential movement of the fender.

In an engine driven vehicle, a body provided with an opening, a drum located in such opening and exposed partly within and partly without the vehicle, said drum being connected in the exhaust conduit of the engine. a fender movable circi1mferentially about the drum and partially inclosing the same, said fender adapted to cover that portion of the drum without the vehicle; when moved to expose the drum within the vehicle, said fender consisting of an outer shell and an inner insulating lining, and

means for restraining the circumferential movement of the fender.

4. In an engine driven vehicle, a body provided with an opening, a drum located in such opening and exposed partly within and partly without the vehicle, said drum being connected in the exhaust conduit of the engine. a grating over the drum. a fender movable circumt'erentially about the drum and partially inclosing the same, said fender adapted to cover that portion of the drum without the vehicle when moved to expose movable in said slot for positioning the fender over the drum.

5. In an engine driven vehicle. a body provided with an opening, bearing-heads secured in the ends of such opening. a heating drum located between said heads and exposed partly within and partly without the vehicle. said drum connected in the exhaust conduit ot the engine. and a, cvlindrical fen dcr movable circumfcrcntiallv about said drum. said fender adapted to cover that portion oi the drum without the vehicle when moved to expose the drum within the vehicle.
